LAM PLIG HTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 629,431, dated July 25,1899. Application filed January 21, 1899. Serial No. 702,944. (Nomodel.)

To all whom-it may concern:

, Be it known that I, FRANK A. CORTlS, of

Meriden, in the county of New Haven and State of Connecticut, haveinvented certain '5 new and useful Improvements in Lamplighting Devices,of which the following is a full, clear, and exact description, wherebyany one skilled in the art can make and use the same.

My invention relates more especially to the class of lamps using gas asan illuminating fluid; and the object of my invention is to provide adevice that shall have material advantages as an aid in the operation oflighting a lamp.

To this end my invention consists in the device as a whole, in thecombination of parts, and in the details and their combination, ashereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side view of a lamp embodyingmyimprovement. Fig. 2 is a detail view,-in central vertical section, ofthe valve, on enlarged scale, looking from the rear of Fig. 1 and withparts in position with the by-pass open. Fig. 3-is a like view, but withthe parts in the position with the main fiuidway open and the by-passclosed. Fig. is a detail side view of the valve with the mainvalve-lever removed and the auxiliary lever in position with the bypassclosed, the position of the auxiliary lever with by-pass open beingshown in dotted lines. Fig. 5 is a like View with the main valve-leverin place, but broken away, the position of the main valve-lever with themain fluid-way of the valve open being shown in dotted outline. Fig. 6is a like view showing the parts in position with the main fluid-way ofthe valve open and the by-pass closed.

My invention-finds a ready application to the class of lamps employinggas as an illuminating fluid and amantle for in creasing the brilliancyof the light, and such a device has been selected herein for the purposeof' disclosing the invention.

In the accompanying drawings the letter a denotes a 'su pply-pipe forsupplying gas to the lamp; 1?, the air-shutter, c the gallery,

' and d the mantle, of a lamp of the class above 50 described and ofordinary construction. In

lamps of this class it is desirable to apply flame to the burner beforea sufficient quantity of gas has been admittedthereto the explosion ofwhich would result in serious injury to the fragile mantle, and in myimproved device I have provided means whereby such a result maybeattained in a ready and effective manner.

A valve-body c is located in operative relation to the burner and isprovidedwith a valve f, the fluid-way f through which communicates by apassage g direct to the lower part of the burner of the lamp. The valvef has also a by-pass f that leads to a ladder h in a certain position ofthe valve, in the form shown this result being attained when the valvehas been but partially moved in the opening operation of the valve. Theladder h leads from this by-pass to a point'preferably near the base ofthe mantle (Z,

The spindle 2' of the valve is provided with a main valve-lever Z0 andan auxiliary valvelever Z, the former being rigidly secured to thespindle, but the latter having a limited rotary movement independent ofthe valvespindle. These levers are supported on a re-' duced portion ofthe valve-spindle, a pin m projecting from the shoulder formed by thisreduced portion into a recess Z in the'edge of the opening in thevalve-lever Z, this construction allowing a limited movement of theauxiliary valve-lever independent of the valve-spindle. Thisauxiliary-lever is employed for the purpose of opening the by-passageonly to admit gas to the burner for lighting purposes. This lever ismoved to an extent to open said by-passage only and is returned to itsclosed position in the closing movement of the valve. A recess Z isformed in the outer edge of the auxiliary valve-lever and engages astope on the valve-body c, this stop limiting the rotary movement of thelever Z.

The main valve-lever has a recess 70 in its outer edge, that alsoengages the stop 6 to limit the rotary movement of the lever, this stopby engagement with the recesses in each of the levers, as described,controlling the movement of the valve and determining its open andclosed positions, and also the po- IOO sition of the valve in itsintermediate position to communicate with the passage through the ladderh. The outer end of the main valvelever extends beyond the outer end ofthe auxiliary valve-lever, so that the former may be moved independentof the latter.

The operation of the device is as follows: The several parts being inthe position shown in Fig. l of the drawings, the auxiliary valvelever Zis moved upward until the end wall of the recess 1 encounters the stop8. The parts are then in the position shown in Fig. 2, with the by-passadmitting fluid to the ladder h. The main valve-lever is now movedupward, carrying with it the valvef, the pin m on which moves aroundinthe recess Z in the auxiliary valve-leverl to the position shown in Fig.6, the main fluid-way through the valve being open and the by-passclosed, as shown in Fig. 3 of the drawings. The parts being in theposition shown in Fig. 2, flame is applied to the lower part of theladder and travels along the same to the base of the mantle. The partsbeing now moved from this position to that shown in Fig. 3, fluid isadmitted through the main fluid-way to the burner, but before the flameon the ladderhas been extinguished and which serves to light the lamp,this being accomplished before a sufficient quantity of fluid has beenadmitted to the burner the explosion of which would seriously injure'themantle.

It is to be understood that my invention is not limited to the precisemeans of accom plishing this result as herein shown and described, anymeans involving the use of a lever pivoted on the valve to rotate thesame, but having independent rotary movement thereof for the purpose ofadmitting fluid to the burner through a separate passage and before themain fluid-way of the valve is fully opened, coming within the scope ofmy invention.
